For developing an OpenSea clone, a robust technology stack would include Ethereum for blockchain, IPFS for decentralized storage, and Web3.js for interaction with the blockchain. Backend can be managed using Node.js, while the frontend could be built with React.js.
Using an existing solution like Appkodes OpenSea clone can expedite the development process by providing a ready-made platform that can be customized as needed. This allows you to focus on adding unique features and scaling the application, rather than building from scratch.
